I believe everyone is right.PVCIt is widely used in construction, transportation and household goods,PVCIt is flame retardant, and various additives are added to make it not flame retardant. We can join them.flame retardant, yes.PVCProducts with flame retardant properties, the following small series and everyone together to explore this problem.

No flame retardantPVCOnce the fire will cause the rapid spread of the flame and expand the thick smoke and toxic gas, to the fire and people's lives and property to bring huge losses. In particular, in recent years, fires have continued in our country,Only by building decoration materials,There are hundreds of accidents caused by the burning of plastic products such as electronic appliances. This has become a serious social problem.

Therefore, endowedPVCProducts to flame retardant has become a top priority. Many countries have formulated various flame retardant standards for polymer materials, and products that do not meet the flame retardant standards are not allowed to be sold. The United States about.10%The plastic products are flame retardant, so the amount of flame retardant is large. It is second only to plasticizer in plastic additives, accounting for the second place. Our country lags behind foreign countries in this respect, so we needPVCWire, cable,PVCDecorative materials and daily necessities and other engineering plastics to add flame retardants to meet the national flame retardant standards.

China's flame retardants in the chlorine system accounted.69%The inorganic system only accounts for the flame retardant.17%About half of them are s.b2O3However, aluminum hydroxide and magnesium hydroxide are less10%The domestic halogen system accounts for about the entire flame retardant.80%At present, foreign flame retardants are mainly inorganic systems, accounting for the overall50%～60%And mainly aluminum hydroxide, magnesium hydroxide.

InPVCThe addition of flame retardant in the product can significantly improve the flame retardant performance of the material, so as to meet the national standards. WithPVCIn the development of electrical appliances, electronics, machinery, automobiles, ships, aviation, aerospace and chemicals, the impact onPVCThe flame retardant requirements of products are also getting higher and higher, so that the development, production and application of flame retardants and flame retardant materials can be developed rapidly, so that flame retardants andPVCdevelopment complement each other.
